This test method covers the procedure for determining the abrasion resistance of either concrete or mortar surfaces using the rotating-cutter method. The method involves an abrasion device, a rotating cutter, a balance and a leveling plate. The surface description, size, and finish type of the specimen, as well as the concrete compaction, age, and strength; applied surface treatment; abrasion time; load used; depth of wear; mass loss; and abrasion time are reported. This test method has been successfully used in the quality control of highway and bridge concrete subject to traffic.

Significance and Use
4.1 This test method gives an indication of the relative wear resistance of mortar and concrete based on testing of cored or fabricated specimens. This test method has been successfully used in the quality control of highway and bridge concrete subject to traffic. Primarily intended for use on the top ends of 152-mm [6-in.] diameter concrete cores, mortar specimens, or other samples of concrete of insufficient test area to permit the conduct of tests by Test Method C418 or C779/C779M, this test method is also applicable on concrete surfaces in place by measuring the abrasion loss as described in Section 10, Procedure B, of Test Method C779/C779M.
1.1 This test method covers a procedure for determining the resistance of either concrete or mortar to abrasion. This test method is similar to Procedure B of Test Method C779/C779M.
1.2 The values stated in SI units or inch–pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non–conformance with the standard.
